It might look like a mug at first glance but it is a really good egg separator! And so easy to use. The whites separate from the yolk and come out the holes in the nostrils... thus the name: It'SNOT a mug. Gross but funny!

Directions:
Break egg into separator.
Tilt the separator downward 45°. Make sure you're tilting over a bowl. If you tilt more than 45° the yellow may reach the nostrils and possibly break - in which case enjoy your scrambled eggs.
When the flow of the egg-white stops, the egg is separated.
